When the remote-as of the BGP peer is the same, the BGP peering become an iBGP peering. Unlike eBGP, an iBGP router will not advertise routes learned from one iBGP peer to other iBGP peers by default. This is the reason iBGP requires full-mesh i.e. all routers peer to each other, or a route-reflecto...

LOCAL_PREF attribute do not traverse external ASNs, thus they are only of local significance i.e. only within your upstream's ASN. Your upstream's LOCAL-PREF attribute will not influence the routing for the whole internet. In global BGP, routes are almost always chosen based on the AS_PATH. It is li...

amity2kare, AS-SETs are not router commands, but are route-object records, which are created in any registered Internet Routing Registry (IRR), e.g. RADB, REACH or NTTCOM. All Tier-1 (global) and Tier-2 (regional) upstream providers build their BGP filters by querying created route-objects (e.g. aut...

Hello MikroTik forums, I've been playing with MikroTik's CHR-6.36.3 images in GNS3 to simulate a dual-stack network. However, it seems like the software's IPv6 route recursive lookups are broken.
